[1] Foreign currency translation adjustments, net of tax, include foreign currency transaction losses at June 30, 2016 of $9 million ($14 million before tax) and December 31, 2015 of $1 million ($2 million before tax) associated with our 2.5% Notes. The 2.5% Notes are Euro-denominated debt designated as hedges of certain of our Euro-denominated net assets. See Note 6 - Debt for more information. The remaining balance in currency translation adjustments excludes income taxes as a result of our current intention to indefinitely reinvest the earnings of our international subsidiaries outside of the United States.
